FLOOR OILEB.

Application filed February 24, 1922. Serial No. 539,049.

To all whomz't may concern:

Be it known that 1, CHARLES W. Comer, a citizen of the United States,residing at VVatertown, in the county of Middlesex and State ofMassachusetts, have invented certain new and useful Improvements inFloor Oilers, of which the following is a specification.

This invention relates to devices for spraying oil upon floors, and itsobject is the eiiecting of the improvements hereinafter set forth.

In the drawings forming pa1t of this specification, Fig. 1 is a centralsectional elevation of an oiler embodying my improvements, parts beingbroken away for shortening the view. Fig. 2 is a detail view 01" aportion of the spray-controlling means. Fig. 3 is a side view of thelower section of the pump cylinder. Fig. 4 is a plan view of a devicefor guiding the lower end of the pump cylinder into its seat. Fig. 5 isa perspective view of the foraminous shield for keeping particles in theoil from reaching and obstructing the action of the pump valve. Fig. 6is a perspective detail view.

The oil container consists of an elongated sheet metal cylinder 1 havingtop 2 and bottom 3, which is filled through a plugclosed opening at 4.The pump cylinder 5 is made longer than the oil container 1 in order toreach the bottom 3 and rise a short distance above the tOp 2, and isthreaded at its lower end, as at 6 in Fig. 3, in order to screw into asocket 7 held by the bottom 3. Near the upper end of the cylinder 5 is athreaded sleeve 8 soldered or otherwise tightly attached thereto, andhaving a shoulder 9. This sleeve screws into an internally threadedcollar 10 held by the top 2, a washer 11 being introduced between theshoulder and collar in order to render same air-tight.

The piston 12 is of well known form, having its rod 13 provided at itsouter end with an operating handle 14, preferably spherical in shape.

Spaced from the lower end of the cylinder 5 is a disk 15, soldered orotherwise fastened in place, and provided with a port 16 closed by aleather flap 17 for preventing the entrance of oil to the cylinder.Through the cylinder wall beneath the disk 15 are three or four openings19 for passage of air from the pump and the entrance of oil from thecontainer, these openings being shielded by a screen 20 for preventingany impurities from the oil reaching the port 16 and, by getting betweenthe latter and the leather flap 17, preventing the tight closure of theport as the piston is being drawn upward.

I prefer to form the shield 20 from a length of foraminous material, asshown in Fig. 5, of proper height to fit between the disk 15 and thelower extremity of the cylinder 5, the elastic pressure of the bentmaterial serving to retain it in position when the pump is removed,while at the same time permitting its easy withdrawal for cleansingpurposes.

Attached to the socket in any suitable way, as by solder, is a ring 21from which rise three or more fingers 22, as shown in Figs. 1 and 4, theobject of which is to guide the lower end of the cylinder down into thesocket 7 when the same is returned to the container.

The spraying cock 23 is of well known construction, communicating withthe space within the lower extremity of the cylinder 5, and opened bymeans of a finger 24 connected by a metal ribbon or link 25 to a fingerpiece 26 positioned at a point conveniently reached by the finger of theoperators hand which is grasping the handle 27. This finger piece 26 isslidably carried in an elongated shield 29 whose lower end is attachedto the container, and whose upper end is attached to the handle 27, andis retained therein by a cross piece 30. The finger piece is preferablyformed by doubling over on itself a length of ribbon metal, one leg 31of which is engaged by the link 25, and the other leg of which is bentup to compose a foot 32 which by its contact with the cross piece 30holds the finger piece from further descent as urged by the spring 33with which the cock and finger 24 are provided.

As shown in Fig. 6, the end of the leg 31 is formed with a link-engagingeye 34 having a leaf 35 behind it whose edge contacts with the shield29, whereby the end of the ribbon can be thrust up behind the leg 31 andwill be guided by the leaf 35 out through the eye 34, after which it canbe bent down to hold it in place.

the oil container is prolongedafar enough below the cook andconnected'parts to per mit the oiler to be stood upon a flat surface tohold itself upright, and t0 ensure the cock and connected parts againstinjury.

In using this oiler, the container 1 is first nearly filled with theoil, and then the piston is reciprocated until a suitable air pressureis secured Within the container to properly expel the oil in a finespray through the spraying cook. The operator tllengrasps the-handleQ'T,with his thumbresting against the-shouldeii36 and his:torefinger-beneaththe finger piece 26 and by pulling upon the latteropens; the cook 23 and begins the spraying operat on, the contain'erbeing sW ung from side to side as he; Walks; along the floor; morderthat a Wide section of the latter can be treated as he advances.
